Abstract

Compounds of the general formula I ##STR1## in which A denotes a radical of the formula A.sup.1, A.sup.2 or A.sup.3 ##STR2## R.sup.1 to R.sup.3 in each case independently of one another denote hydrogen or halogen, PA1 the radicals R.sup.4 in each case independently of one another denote halogen, (C.sub.1 -C.sub.3)halogenoalkyl or nitro, PA1 R.sup.5 denotes (C.sub.1 -C.sub.5)alkyl, which can be halogenated, PA1 X denotes oxygen or sulfur, PA1 n denotes a number from 0 to 2 and PA1 m denotes a number from 1 to 4 with the proviso that (R.sup.4).sub.m does not by itself denote halogen or by itself denote nitro, and where A=A.sup.1, salts thereof which can be used in agriculture, have advantageous acaricidal and insecticidal properties. Processes for the preparation of the compounds of the formula I are furthermore described.
